Anemia is one type of red blood cell disorder. A lack of the mineral iron in your blood usually causes this disorder. Your body needs iron to produce the protein hemoglobin, which helps your red blood cells carry oxygen from your lungs to the rest of your body.
Heat transfer refers to the physical process by which heat energy moves from one area to another. The Heat Transfer Methods figure above illustrates various heat transfer methods. Branches above the fire are receiving heat by convection and radiation.
The energy stored in the soil will radiate out to warm the air, raising air temperatures. 2. Energy in the form of heat, electricity, motion, or sound can change forms and move from one system to another. This can be demonstrated by making a cup of tea. For example, electricity, one form of energy, changes form to thermal energy (heat) through the stove and it transferred by conduction to the water for tea. The cup warms the hands, and the tea warms the insides of the person drinking the tea. This is energy transfer.
